首先下载KB2468871，这个我已下载，并尝试失败而得到上面的日志

试着安装它， 然再下面文件夹里面找缓存文件.
C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Xml.Serialization\v4.0_4.0.0.0__b77a5c561934e089
分别拷贝到 C:\Windows\Microsoft.NET\Framework\v4.0.30319 和 C:\Windows\Microsoft.NET\Framework64\v4.0.30319 目录中
copy C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Xml.Serialization\v4.0_4.0.0.0__b77a5c561934e089\System.Xml.Serialization.dll C:\Windows\Microsoft.NET\Framework\v4.0.30319
copy C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Xml.Serialization\v4.0_4.0.0.0__b77a5c561934e089\System.Xml.Serialization.dll C:\Windows\Microsoft.NET\Framework64\v4.0.30319
然后再安装即可成功。
